You can have clutches with multiple sires but you can not have babies that come out of those eggs that are combos of two of the sires. That's completely impossible..

I bred a leucy (Russo x Lesser) and and Woma, and a Pinstripe, all to a normal female one year.. I ended up with babies of every gene. I had one Lesser, one Russo, two Womas, three Pins, and one normal..

Each father sired at least one baby but there is no way genetically that I would ever have gotten a woma pin, or a lesser pin.. Just can't happen.
